The present paper emphasizes greatly on the development of a simulation model for the single relaying based cooperative MIMO OFDM wireless communication system This paper provides a new insight on system performance comparison with Amplify and Forward relaying protocol, STBC and Spatial multiplexing schemes, four channel equalization techniques (ZF, MMSE, ZF-SIC and MMSE-SIC) and four digital m...

The performance of a direct sequence spread-spectrum land-mobile satellite transmission system, using binary phase shift keying (BPSK) modulation, is analyzed. The satellite channel is modeled as having shadowed Rician fading characteristics. The bit error probability is evaluated, considering both the envelope and the phase variation. Assuming a Gaussian approximation for the interference, num...

In this paper impact of Reed Solomon coding over convolutional coding is analyzed for the different modulation techniques. In this paper communication system model employing GMSK, QPSK, and BPSK modulation techniques are implemented assuming the channel to be AWGN in nature. The simulation results obtained shows that GMSK using Reed Solomon encoding and decoding schemes gives improvement in Bit...

This paper presents the simulation results of digital modulation schemes BPSK and QPSK. Digital modulation is less complex, more secure and more efficient in long distance transmission. The noise detection and correction in digital is more efficient than analog. So it has more importance in modern communication system. These digital modulation schemes can be realized using FPGA ( Field Programm...
